This gives rise to the common name, keyhole cichlid, from which the genus name Cleithracara (meaning "lock acara") is derived.

[4] When the species is startled or nervous it assumes a blotchy colouration and presses its body against rocks or logs in an attempt to camouflage itself.

It is a monogamous, biparentally custodial breeder which spawns on flattened rocks, logs or leaves.

[1] The species is suitable for the community aquarium and will accept a wide variety of prepared fish food in captivity.

The environment in aquaria should mimic the natural habitat of the species and include plants and numerous hiding places.
